NIAOHI-NE- FOR STICKING SAFETY-PINS.

SPECIFICATION forming part of Letters Patent No. 752,229, dated February 16, 1904.

Application filed February 17, 1898. Serial No. 670,625. (No model.)

To all whom; it nwty concern:

Be it known that I, FRANK M. Jonnson, of Waterbury, county of New Haven, State of Connecticut, have invented a certain new and 5 useful Machine for Sticking Safety-Pins; and I do hereby declare the following specification, taken in connection with the accompanying drawings. forming a part of the same, to be a full, clear, and exact description thereof.

has been customary to attach the pins to cards or sheets of paperby'passing the points of the pins through a crimp or loop of the paper and then closing the pins by bringing the points into the guards or catches of the pins. As the finished pins have usually, if not always, been closed it has been necessary in attaching the pins to the cards to open the pins, thrust the points through the paper, and then close the pins, and these operations have heretofore been performed by hand, the paper or card being held between slotted crimpers while the pins were successively stuck thereon.

pins upon cards, paper, or other material.

A further object of the invention is to provide means for separating individual pins from 3 a mass of pins and presenting said pins in the same relative positions.

hen employing all the features of the present invention, the individual pins are automatically separated from a mass of pins and presented to the sticking devicesand arcantomatically opened, thrust through the card, and closed, the card being crimped and held by crimpers. Certain features of the invention, however, may be employed Without employing all the features, if desired. Thus the automatic separating and feeding mechanism may be dispensed with, if desired, and the pins presented to the sticking mechanism by hand. Again, if the pins are open when they are supplied to the machine then the opening devices may be dispensed with. Again, the opening means and means for thrusting the pins through the material might be employed With- In preparing safety-pins for the market it The object of the present invention is to pro- 1 vide means for automatically effecting any or all of the operations performed in sticking the out using automatic means for closing the pins. It will also be understood that the means for separating and presenting the pins may be employed in other relations where it is desired to automatically handle safety-pins. It is preferred, however, to present the pins to the machine in a closed condition and to use means for opening the pins, thrusting them through the cards or other material and closing the pins, and it is also preferred to provide means for automatically feeding the pins to the sticking mechanism, although the pins may be fed thereto by hand, if desired,

without departing from the invention. It is also preferred to embody the invention in a machine which is constructed to simultaneously stick a plurality of pins, although it will be understood that the invention may, if desired, be embodied in a machine in which a single pin is operated upon by the sticking devices.

Any suitable means maybe employed for opening the pins, thrusting them through the card, or closing the pins, or any suitable means may be employed for feeding the pins to the sticking mechanism, and the partioular'construotion of any or all of these devices is not material to the broad invention, which resides in the combinations of means set forth in the claims without regard to the specific structure of such means. 7

For the purpose of illustrating and explaining the invention a machine for simultaneously sticking twelve pins is shown in the accompanying drawings, which machine embodies all the features of' the invention.

Referring to said drawings, Figure 1 is a side elevation. Fig. 2 is a plan view- Fig. 3 is a partial end elevation. Fig. 4: is a sec tional elevation showing apart of the devices for separating and presenting the pins to sticking mechanism. Figs. 5 and 6 are sectional details.

tionsshowing the sticking mechanism in different positions. Figs. 12 and 13 aredetails.

The machine shown in the'drawings is espeoiallydesigned to handlesafety-pins, such Fig. Y, Sheet 1, is a detail of the drum 6. Figs. 8to 11 are sectional elevaas indicated in the drawings, and the peculiarities of said pins are taken advantage of in separating, assorting, and presenting the pins to the sticking mechanism. It will be understood,however, that other forms of devices may be used for this purpose 'and that the form of devices used will vary with the form and peculiarities of the pins' being handled. The particular sticking devices shown are of more general application and may be used to handle various forms of pins.

Referring now to the specific machine shown and to the drawings in detail, the pins are placed in a hopper 1, through which a series of traveling pins or projections 2 pass. These pins may be formed on any suitable traveling surface and are shown secured to the periphery of a drum 3, which forms one wall of the hopper. The pins 2 are arranged in circumferential rows about the drum 3, the number of rows difiering with the number of pins to be simultaneously thrust through the card or paper by the sticking mechanism. As the pins 2 pass through the mass of safety-pins in the hopper the safety-pins are caught upon the pins and separated from the mass. These safety-pins a are carried up over the top of the drum 3 and are stripped from the pins 2 by the ends of guides 1, formed on a guideplate 5. The surface of the guides 4:, forming the walls of the guide-grooves in the plate 5, are divergent at the entrance end of the grooves, but gradually assume a parallel position toward the discharge end, so that as the safety-pins a slide down said grooves they are turned on edge, Figs. 4, 5, and 6. At the end of the guide-plate 5 is a rotating grooved drum 6, which forms a device for arranging the pins (0 with their points all pointing in the .same relative direction. The drum 6 is provided with grooves 7, which register with the grooves in the plate 5, and these grooves 7 are wide enough to admit the passage of the coil end of the pins, but not wide enough to allow the passage of the catch end of the pins. If the pins come down the plate 5 with the coil end foremost, they pass into the grooves 7 up to the catch 6 and then are carried over and delivered onto guide-rails 8, the space between which is the same width as the Width of grooves 7. When a pin comes -down the plate 5 with the catch end foremost,

the'end of the pin is carried forward by the drum 6 until the coil end leaves the plate 5, when said coil end falls into the groove 7 and the pin is then transferred to the guides 8. Thus the pins are arranged by the action of the drum 6 with their points extending upward. The guide-rails 8 are inclined, and the pins slide down said guides, some of said pins having the point side foremost and some having the back side foremost. the guides 8 the pins which have their points in the proper relative position to be transferred to the sticking devices are selected and 1 At the ends of the other pins discarded and allowed to pass out of the machine. The selecting mechanism is as follows: The ends of guides 8 may be notched to form short horizontal platforms or rests 9, Figs. 8 to 11, and in the rear of said platforms is located a plate 10. A stop-bar 11 is arranged in advance of the platforms 9. As the pins (0 come down the guides 8 the coil ends of said pins are arrested by the plate 10. Should the point side of the pin be foremost, then the catch 6 of the pin will rest on the platform 9, when the end of the pin engages the stop 11, and the pin will be retained in the machine. Should the back side of the pin be foremost, however, then the coil 0? of the pin will pass beyond the end of platform 9, when the end of the pin engages the stop 11, and such pin will fall down into the chute 12 and be directed out of the machine. Thus the pins presented at the ends of the guides 8 will always be in the same relative position, each pin having its point extending forward and its point side in front.

The pins are withdrawn from the selecting devices and transferred to the sticking mechanism by a reciprocating bar 13, provided with fingers or hooks 14 for engaging the ends of the pins. This bar moves rearward to bring the laterally-extending ends of the hooks 1 1 into line withthe ends of the pins (1, which are presented at the ends of guides 8. The bar 13 then moves laterally to insert the hooks in the ends of the pins, and then moves forward to withdraw the pins and carry them forward into a position to be delivered to the sticking devices. The stop-bar 11 is carried by two pivoted arms 13 and is held yieldingly in position by a spring 14:, Figs. 1 and 3. As the pins are carried forward the stop 11 yields to allow the passage of the pins, and the coil ends of the pins pass off of the plate 10 and swing down, as shown in Fig. 10. The pins are guided in their forward movement by strips 15, extending forward from the ends of the guides 8, but sufficiently far apart to allow the passage of the catch end of the pin between them. Below the strips 15 are guide-partitions 16, provided with laterally-projecting ribs 17,

the space between the ribs being sufficient to allow the passage of the wire of the pin a, but not sufficient to allow the passage of the coil end of the pin. As the pins are carried forward by the bar 13 the coil ends strike the ribs 17 and are arrested, while the catch ends are carried into position above the passages in front of the ribs 17. The bar 13 is now moved laterally to withdraw the hooks 14 from the pins, which pass down between the plates 16 to the sticking devices, the catch ends of the pins passing in front of the ribs 17 and the coil ends back of said ribs. The upper ends of ribs 17 are inclined at 18 to insure the passage of the catch end in front of said ribs. The pins are thus presented to the sticking mechanism in the same relative position, with the points extending forward and with the point side down. In order to agitate the pins, which rest one above another between the guides 8, so that there will be no danger that they will become 7 wedged or cramped, the plate 10 may be pivoted, if desired, and may be vibrated about the pivot. An agitator-plate .16 may also be arranged just behind the stop-bar 11, if desired. As shown, the plate is engaged by a pin- 10', secured in an arm 11, secured to a rockshaft 12, which is oscillated by a cam to be described. The plate 16 is carried by arms 17 secured to a rock-shaft 18, which is operated by a cam to be described.

Should the space betweentwo of the guides 8 become filled with pins, the delivery of pins to such space may be stopped by one of a series of strippers 19, pivoted on a rod 20. above the drum 3 and arranged to be swung against the face of the drum and strip the pins a from the pins 2.

A rotating brush 21' may be arranged adjacent the surface of the drum 3 to prevent the pins 2 from carrying more than one pin forward at a time. A series of guides 22" may be mounted on the rod if desired, and arranged to extend to the ends of the guides 4 and serve to more accurately direct the pins to said guides.

The sticking mechanism, which is located below the partition 16, will now be described. Plungers or pushers 19 are secured to a reciprocating plate 20 and move in slots or grooves 21, formed in the plate 22. The plungers are grooved on the upper edge to center the pins over the grooves 21. When the pins pass down between the plates 16, they are delivered upon the tops of plungers 19, Fig. 8. The plungers then move back from beneath the pins, the pins being prevented from backward movement by a bar 23, extending transversely above the plungers, Fig. 9. The plungers then move forward, carrying the catch ends of the pins under a plate 24, extending transversely across the machine in front of the plate 16 and above the plate 22. The ends of the plungers are recessed at 25 to overlie I the coil end of the pins and prevent them from rising under the action of the opening devices. The pins are opened by the action of a series of pins 26, which are mounted in the plate 22 below the grooves 21 and are provided with beveled ends 27. When the pins 26 are moved up into the grooves 21, the beveled ends 2'7 engage the points 0 of the pins (0 and lift said points out of the catches b and at the same time crowd said points laterally, so that when the pins 26 are withdrawn the points 0 do not reengage the catches, but rest upon the bottoms of the grooves 21.

The crimping devices consist of a male 'crimper in the form of a vertically-reciproa transverse recess 29 in the end of plate 22 and extending above the bottom of the grooves 21. The crimper-bar 28 is provided with a series of grooves 30in its upper edge for the passage of the pin-points. While the pins are being opened the card, paper, or other material c, to which the pins are to be applied is inserted between the crimpers, Fig. 10, and the male crimper is raised into the female crimper and the paper is orimped, Fig. 11. The plunger then moves forward, thrusting the points of the pins through the crimp in the paper, the points passing through the grooves 30 and the pins being held in the grooves 21 by a plate 31. The bottoms of the grooves 21 may be curved or V-shaped to guide the points into the grooves 30. The plungers continue to move forward until the catch ends of the pins are projected beyond the plate 31 and brought under a closing-bar 32. The bar 32 is provided with a series of depending fingers 33, which are normally at one side of the grooves 21. When the pins are brought under the bar 32, said bar moves downward and laterally to carry the catch 6 down past the points 0 and then laterally in the opposite direction to bring the catches into line with the points, so that when the crimper 28 and the closer-bar 32 move back the points will engage the catches; The fingers 33 are preferably so shaped that they will engage only the catch side of the pin 9 5 and will tend to twist the catch laterally rather I than to move the end of the pin bodily to one side. While the pins are being closed a new set of pins are being delivered upon the tops of plungers 19, Fig. 8. l/Vhen the pins have been thrust through the paper and closed and the crimper has moved back, the filled card or paper is removed and a new card inserted.

The parts are given the various movements described by mechanism driven from the driving-shaft 34, on which is loosely mounted a driving-pulley 35. The pulley may be connected to or disconnected from the shaft 34 by -means of a clutch 36, which is operated by a lever 37. A pulley 38 is secured to the shaft 34 and is connected, by means of a belt 39, with a pulley40 on a short shaft 40. The drum 3 is driven from the shaft 40 by means of a belt 41, which runs over said shaft and a pulley 42, secured to the shaft 43 of thedrum. A belt-tightening pulley 44 engages the belt 41, and by adjusting said pulley by means of the lever 45 the speed of the drum may be varied or its movement stopped altogether. The drum 6 is driven from the shaft 43 by means of a belt 46, which runs over a pulley 47 on said shaft and a pulley 48 on the shaft of drum 6. The plate 20 is operated by means of a cam-groove formed in a disk 49 on shaft 34, which groove is engaged by a roll on the end of arm 50. secured to said plate, Fig. 13. A bevel-gear 51 is secured to shaft 34 and engages a bevel-gear 52 on a side shaft 53,which carries the cams for operating the plateslO and 16, the opener-pins 26, the crimper 28,

and the closer-bar 32. The rock-shaft 12 is rocked to vibrate the plate 10 by means of a cam 54, which engages a roll on the end of -arm 55, secured to shaft 12, and rock-shaft 18' is vibrated by a similar cam 56, which engages a roll on the end of a similar arm secured to shaft 18.

The opener-pins 26 are provided with pins 57, which engage slots in the ends of arms 58, secured to a shaft 59. The shaft 59 is rocked to operate the pins 26 at the proper time by a cam 60 on a shaft 53, which engages a roll on an arm 61, secured to the end of shaft 59.

The crimper-bar 28 is provided with a shank 62, which is guided in a standard 63, and said shank is engaged by the end of an arm 64:, secured to shaft 65 and extending through an opening 66 in standard 63. An arm 67 is secured to the end of shaft 65 and carries a roll 68 at its upper end. A cam 69 on shaft 53 engages roll 68 and operates the crimper-bar.

The closer-bar 32 is mounted in guides 7 O at the sides of the machine and is connected to the arms 71 by means of a link 7 2. The

arms 71 are secured to a shaft 73, which hasv another arm 74, secured to the end thereof.

' A cam 75 engages a roll on the end of said arm and rocks the shaft 7 3 to give the closer-bar its up-arid-downmovement. The bar is given its lateral movement by means of a cam-slot 7 6 in one of guides 7 O, which is engaged by a pin 7 7 on the end of the bar 32.

The bar 13 is connected at one end to the end of a slide 78 by a pin-and-slot connection, so that said bar may have a slight lateral movement on said slide. The other end of bar 13 is pivoted to one end of a bell-crank lever 7 9, pivoted to a short slide 80. The other end of the lever 79 .is connected bya link 81 to a slide 82, which is connected to slide 80, so that there may be aslight lost motion between the slides, Fig. 12. The slides 7 8 and 82 are guided in the plate 22 and are reciprocated by camgrooves 83, formed in disks 84: on shaft 34. The grooves 83 are engaged by rolls on arms 85, secured to the slides 78 and 82. Supposing the slides to have been drawn back to bring the hooks 1 1 into line with the ends of the pins, the slides and 82 will be as shown in Fig. 12. The slide 82 is now moved forward, and owing to the lost motion between slides 82 and 80 the lever 7 9 will be rocked to move the bar 13 laterally and carry the hooks 14. into the ends of the pins. The shoulders 86 are also brought up to shoulders 87, and further forward movement of the slide 82 moves slide 80 and the bar 13 forward. When the slides have reached their forward limit and slide 82 starts back, the slide 80 remains at rest and the lever 7 9 is rocked to move the bar 13 laterally and withdraw the hooks 1 1 from the pins. When the shoulders 88 engage, the slide 80 then moves back with slide 82. The cam-grooves in disks 84: are so shaped that the slide 82 begins to move in such direction an instant before'the slide 7 8 begins to move, so that slides 80 and 7 8 move in unison. It is not intended to claim herein any of the previously-known devices for separatingand conveying staples, buttons, and the like.
